thermal fracture

The boundary integral equations, in which fictitious boundary forces are taken as the unknowns, for harmonic thermal fracture problems of the finite body with multiple cracks and mixed boundary conditions are proposed.

给出了无限平面作用有简谐变化的点热源时的位移场、应力场基本解、用间接法构造出混合边值多裂隙体在简谐变温场作用下的热断裂问题的边界积分方程,并离散求解。

The anomalies are controlled by tectonic factors;fault heat conduction is the major feature of the geothermal anomaly in the area.

地热异常分布主要受区域构造因素控制,断裂导热是本区地热异常的主要特点。
